Hello Chris, I maybe back to ask the price, thanks for the offer.

Hi Mark, I think so, why what is it todo with the aircon ?

If not correctly connected it will stop the pump engaging.

It provides the path to 0v for the low side of the pump and opens if the rad temp gets to high (the heat produced by the aircon heats the evaporator in front of the radiator up and hence lowers the cooling capacity of the rad by pre-heating the cooling air)

[Richard A]

O' sh1t, didn't understand, will check in the morning, what happens if the unit is not working, will the connector still carry the single to the aircon pump ?

I think the key here is that the 150g charge they have added (where did that figure come from?) is not likely to bring the pressure up high enough to bring the pump into operation. They should be able to monitor the low side and high side pressures with the air con kit they have connected. As Mark says, until the low side is relatively close to the fully charged pressure the system will be completely disabled. Not sure what electronic gizmos will tell them. Tech 2 or equivalent will not tell them anything. It's the 2 pressures and the volume of refrigerant added that are important.

Thanks "dbug", yes that is what went on (your weight maybe a bit high). Update: the aircon compressor pulley rotating ok, but the front plate is still, can rotated by hand without a problem.

No gas weight is correct for 98 2.5 V6 Elite!!  Also 155gm lub oil required.  Irrespective if enough lo pressure to allow clutch on compressor to engage, if clutch f*cked (seized) it will never engage.  It costs no money to check whether it is seized!  If seized the first thing u must do is replace it b4 doing anything else which may cost otherwise any cost u incur could be wasted.  Check it out as my previous reply.  Note the compressor is an rsol to swap out - i know i've done one.

Bad news for you .. perhaps ..

The compressor on mine went, contaminated the whole system, caused the expansion valve to fail open, and partially blocked the filter/dryer...

Local air con shop did a reasonable job .. but the total bill was just over £900 ...

Major expense was a full system flush to get all the crap out and I saw what was in the pipes before they started .... horrible dark grey viscous gunge which if you rubbed a drop between your fingers you could feel the metallic particles .. it felt like fine valve grinding paste.. ..

Followed by a Compressor, Expansion valve, filter dryer +  labour to change ..

2nd user compressor - £30, +£45 to vac system, check for leaks and gasup/lubricate etc - A/C  
U were very unlucky

[Entwood]

I don't think a normal vac would have shifted the crap, so agreed to the flush .. seemed a tad daft to fit new parts to a contaminated system.

I went for the "full monty" repair as I've only just bought the car (January) with the intention of keeping it along time ... at least it now has a 2 year warranty on the air con system !!!

[sassanach]

did they change the condensor?

[Entwood]

did they change the condensor?

Nope .. they said the flush would clean it sufficiently ...   :-/

[sassanach]

you cant effectively clean a condensor,but you have a 2 year guarentee therefore it will be their problem if you have a problem

[sassanach]

the only condensor you can really clean is a serpentine condensor,practically obsolete for 30 years

[Entwood]

you cant effectively clean a condensor,but you have a 2 year guarentee therefore it will be their problem if you have a problem

I'm guessing if it lasts 2 years it'll last longer .. ie .. any failure wil occur quickly ??

At least I hope thats the way it works .....  :-/ :-/

[sassanach]

believe me if anything is going to happen as a result of not changing the condensor, it will happen well within 2 years.

Was going to say £30 for the compressor second hand +p&p
